Raspberry plant named ‘DrisRaspOne’

ABSTRACT

This invention relates to a new and distinct cultivar of raspberry plant named ‘DrisRaspOne’. A new cultivar primarily characterized by its large plant size, high productivity with a long fruiting season, large fruit with a medium red color and a high percentage of titratable acidity is disclosed.

Genus and species: Rubus ideas L.

Variety denomination: ‘DrisRaspOne’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct raspberry cultivar designated ‘DrisRaspOne’ and botanically known as Rubus ideas. This new raspberry cultivar was discovered in Santa Cruz, Calif. September, 2002 and originated from a cross between the female parent ‘T186.1’ an unpatented proprietary raspberry plant and the male parent ‘Driscoll Maravilla’ (U.S. Plant Pat. No. 14,804). The original seedling of the new cultivar was asexually propagated at a nursery in Santa Cruz, Calif. ‘DrisRaspOne’ was subsequently asexually propagated and underwent further testing at a nursery in Santa Cruz, Calif. for five years. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new cultivar at various stages of development as nearly true as it is possible to make in color reproductions.

DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘DrisRaspOne’ is based on observations taken from the 2003 to 2007 growing seasons in Santa Cruz, Calif. This description is in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘DrisRaspOne’ has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
